How to Store String and Integer Values in a Single Struct in Go?

Declaring and Using a Struct Field to Store String and Integer Values

In Go, you may encounter situations where you need to store values of different types within a single struct. While the example struct provided handles string and boolean values, you may also require handling integer (int) input.

However, the Go programming language does not natively support using a single field to store values of different types. Go's type system operates on distinct and immutable types.

To address this, you have two options:

1. Type Casting:

   • You can convert the int input to string and convert it back to int while processing the input.

2. Multiple Structs:

   • You can define separate structs, such as testCaseInt and testCaseString, each dedicated to handling specific input types.

Note that Go 1.18 will introduce sum types, which would provide a more elegant solution to this problem. However, for earlier versions of Go, you will need to utilize one of the aforementioned approaches.
